I think these (the airport pictures) say one of 2 things. Either the romance has gone sour or is over or she is just extremely tired from the ball. You would think if she were in love she would be smiling , dreaming over the night before. But I dont know. Also if Albert were truly in love he would be holding her hand kissing it(despite protocol) or a loving glance. I mean Mary and Frederik behaved like they were madly in love within protocol limits.
